plaza right by the pedestrian bridge but some prices are much higher than other pharmacies and some are lower.

Is there a hidden gem of a pharmacy that's off the beaten tourist path of Revolucion that has lower prices? I don't need Viagra but am looking for good prices on Pravachol, Prilosec, Ambien, antibiotics and blood pressure meds (they're not all for me - I'm not in that bad shape yet!).
